<P>PROBLEM TO BE SOLVED: To consistently and smoothly execute the high-speed casting even when the amount of lubricant is reduced, to control occurrence of breakout and generation of any lubricant reaction product, and to considerably reduce any defective ingot. <P>SOLUTION: A continuous casting apparatus for manufacturing an aluminum alloy cast bar by supplying a molten alloy 255 in a molten metal receiving part 250 from one end of a casting mold 201 into the casting mold 201 includes heat insulating members 2 (2a, 2b) having a molten metal pouring passage 211 which is arranged between the molten metal receiving part 250 and one end of the casting mold 201 to communicate the molten metal receiving part 250 with the casting mold 201, and a refractory-made plate-like body 210 provided along the heat insulating members 2(2a, 2b) and a partition layer 2c having a through hole integrated with the molten metal pouring passage 211. The casting mold 201 is arranged horizontally, and the partition layer 2c is formed of a material capable of preventing passage of the lubricant and the vaporized lubricant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
